Abstract. Voigt wave propagation was investigated in a homogenized composite material (HCM) arising from a porous electro-optic host material infiltrated by a fluid of refractive index na. The constitutive parameters of the HCM were estimated using the extended Bruggeman homogenization formalism. Numerical studies revealed that the directions which support Voigt wave propagation in the HCM could be substantially controlled by means of an applied dc electric field. Furthermore, the extent to… 

On the propagation of Voigt waves in energetically active materials

If Voigt-wave propagation is possible in a dissipative anisotropic dielectric material characterised by the permittivity dyadic ε ̿ , then it is also possible in the analogous energetically active

Dyakonov–Voigt surface waves

The fields of the new surface waves, named Dyakonov–Voigt (DV)surface waves, decay as the product of a linear and an exponential function of the distance from the interface in the anisotropic medium, whereas the fields ofThe Dyak onov surface waves decay only exponentially in theAnisotropicmedium.

Anisotropic dielectric materials characterized indefinite permittivity dyadics (known as hyperbolic materials) were investigated for possible optical sensing applications. Such materials present

Surface-plasmon-polariton wave propagation supported by anisotropic materials: Multiple modes and mixed exponential and linear localization characteristics

The canonical boundary-value problem for surface-plasmon-polariton (SPP) waves guided by the planar interface of a dielectric material and a plasmonic material was solved for cases wherein either

Voigt-wave propagation in active materials

If a dissipative anisotropic dielectric material, characterized by the permittivity matrix $\underline{\underline{\epsilon}}$, supports Voigt-wave propagation, then so too does the analogous active

From unexceptional to doubly exceptional surface waves

An exceptional surface wave can propagate in an isolated direction, when guided by the planar interface of two homogeneous dielectric partnering mediums of which at least one is anisotropic, provided

On the sensitivity of directions that support Voigt wave propagation in infiltrated biaxial dielectric materials

Abstract. Voigt wave propagation (VWP) was considered in a porous biaxial dielectric material that was infiltrated with a material of refractive index na. The infiltrated material was regarded as a

Correlation length facilitates Voigt wave propagation

Under certain circumstances, Voigt waves can propagate in a biaxial composite medium even though the component material phases individually do not support Voigt wave propagation. This phenomenon is

Voigt waves in homogenized particulate composites based on isotropic dielectric components

Homogenized composite materials (HCMs) can support a singular form of optical propagation, known as Voigt wave propagation, while their component materials do not. In essence, Voigt waves represent

The Bruggeman formalism for the homogenization of particulate composite materials is used to predict the effective permittivity dyadic of a two constituent composite material with one constituent

Voigt wave propagation in biaxial composite materials

The propagation of Voigt waves in biaxial composite materials—whose component material phases do not support the propagation of Voigt waves—is demonstrated. Orientations of the singular axes (along

The effective permittivity dyadic of a composite material containing particulate constituent materials with one constituent having the ability to display the Pockels effect is computed, using an

Homogenization of linear bianisotropic particulate composite media - Numerical studies

We present here the application of the Maxwell Garnett (MG) and the Bruggeman (Br) formalisms to homogenize very general linear bianisotropic-in-bianisotropic particulate composite media with

Nonlinear optics.

In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
